Ursula next appears briefly in "The One with the Jam", where she is being stalked by Malcolm (David Arquette) who mistakes Phoebe for her.

In "The One with the Jellyfish" Phoebe tells Ursula that she has met their birth mother (Teri Garr), but Ursula already knows about her. In "The One Where Chandler Can't Cry", Phoebe starts getting unwanted attention from men, and discovers that Ursula is starring in pornographic films using Phoebe's name, including a film called Buffay The Vampire Layer. Phoebe gets revenge by claiming Ursula's paychecks and embarrassing her many male fans. Flashbacks in "The One Where They All Turn Thirty" reveal that Ursula sold Phoebe's birth certificate to a Swedish runaway, and that both sisters are thirty-one, not thirty. In "The One with the Halloween Party", Ursula introduces Phoebe to Eric (Sean Penn), her fiancé. Phoebe is horrified that Ursula has lied to Eric that she is a teacher, a member of the Peace Corps, a non-smoker, and attends a church group; so she tells Eric the truth, upon which he breaks up with Ursula. The series finale of Mad About You, set 22 years into the future, reveals that Ursula becomes Governor of New York.
